What's the experience levels? Red's footwork and handwork are both meh. He's consistently coming in with one unfocused punch. The footwork looks unpracticed. The hands on the side of the head is positioned such that his jabs are chopping down instead of going straight in.

Your form looks better, but you're also doing one thing then backing off, and some of your dodging techniques were pulling the head straight back, which could be improved.

Overall, I'd say that there should be more exchanges that aren't 1 punch long.

Permalost picked up on more stuff than I did at a glance. Basics first, stay up on the balls of your feet & utilize set-ups and combinations. The single technique and retreat won't do you a lot of good.

I'd work on throwing combos, like the lads above me pointed out. That means you'll have to adjust to staying within distance a bit longer, rather than landing a jab and getting out of there.
And head movement I guess - I'd try and work some more slips into your form, rather than just swaying backward.
Other than that, just try and make sure that your punches are sharp, clean and deliberate. But that's just a matter of some bag-work and shadow-boxing.

You are leaning back as you throw your jab, exposing your chin for a counter. Chin should stay tucked behind your shoulder on jab extension. Stay on the balls of your feet, don't fade out as you jab. You are losing power, reach, and putting yourself at risk.

More head movement just before entry can make it harder for your opponent to target.

Work more combos. You only threw a handful of shots with your right. Part of this may be due to the fact that you are leaning away on your jab, which keeps you out of range for a follow up with your rear hand. If you're coming up short on your jab, double jab, continuing to shuffle in. When the jab sticks, follow it up with a cross.

Chin down. Keep your chin down more. You are generally keeping your hands up which is good, but occasionally your jab comes out low, you lean back a bit, and your chin is up. This is really bad.

You are moving around moderately well. Keep this up, but focus on staying on the balls of your feet, and look for more opportunities to press in. Move around, and when you see your opponent starting to adjust, press in and catch him off balance. It'll be tough for him to throw if he's still adjusting, trying to square up.
